Mybatis和Spring整合过程报Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

从SqlSessionDaoSupport 这个类的源码中可以看出，原因是mybatis-spring-1.2.0中取消了自动注入SqlSessionFactory 和 SqlSessionTemplate

解决办法：创建一个Dao的基类DaoSupport，让这个基类继承SqlSessionDaoSupport，并通过set方法注入SqlSessionFactory属性即可：

public class CommonDao extends SqlSessionDaoSupport {
    @Resource
    public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory){
        super.setSqlSessionFactory(sqlSessionFactory);
    }
}

然后让Dao实现类再继承这个DaoSupport基类即可：

@Repository
public class PersonDaoImpl extends CommonDao implements PersonDao {
  //....... 
}
